When looking at a large area, the emissivity of various surfaces must be considered. Most materials found on the surface of buildings will have a relatively high emissivity but there will still be noticeable differences in the perceived image due to a change in surface material.
This can be overcome by a detailed knowledge of the building under investigation. Some metals and glass can reflect infra-red radiation and apparent hot spots can be a reflection from a hot object near by.
A thermal imager detects and displays surface temperatures. The surface temperature under normal conditions is the result of heat energy conduction through the walls from a heated object or internal room. Moisture is an excellent conductor of heat and when insulation (like glaswool or open cel insulation) is damp it will become a conductor rather than an reflector or insulator. A measure of the ability of a surface to radiate energy as measured by the ratio of the radiant flux per unit area to that of the radiated by a black body at the same temperature.
Example: Black Body = 1.00
Red rough house brick = 0.93
C3 ADF foil = 0.055
Moisture is an efficient conductor of heat. Wet or damp renders your insulation and or your mission not to be detected useless.
C3 Anti Detection foil is not hygroscopic

Can-Fan Digital EC Fan Controller full feature environmental control Can Fan introduces LCD EC Fan Controller, an advanced climate controller with LCD Screen, that allows you set temperature and humidity, besides other interesting functions like hysteresis, negative pressure, maximum and minimum speed of CAN Fan EC extractors. The Can Fan EC Controller works only in conjunction with Can Fan EC extractors, built with most modern technology, being more energetically efficient, and guaranteeing more power and less electrical consumption. • Temperature day • Temperature hysteresis day • Humidity day • Humidity hysteresis day • Minimum speed day • Maximum speed day • Temperature night • Temperature hysteresis night • Humidity night • Humidity hysteresis night • Minimum speed night • Maximum speed night • Negative pressure setting • Switch sensor level • Switch over time day/night
This satellite controller runs AC fans using a stepped transformer linked into the LCD controller. This means the EC controller can run AC fans as well

CAN Inline Carbon Filters are made from Can’s lightweight, high grade carbon and are designed to fit directly into inline in runs of ducting, rather than at the point of extraction. They use the lightweight version of CAN Filter carbon that will last for around 18 months (CAN have a lightweight type and a pelletized type – the pelletized type lasts longer but is significantly heavier). Some growers use them as a belt and braces secondary filter, but as long as you match them with the correct fan and airflow, they are fine to use as a primary filter. As the carbon used is Can’s lightweight type, they will not affect the airflow too much.
